Energy Efficient Solar Homes Built Across Canada in the 1970’s and 80’s

R-2000 Program• Established in 1985• Technical standards based on sound

building science principles• Energy efficiency features determined

through use of Hot 2000 energy analysis software

• Builder training• Homes independently inspected and

certified• Energy consumption typically 60% of

conventional home• Marketing program• Over 10,000 certified R2000 homes built• Has helped to move the industry to

more energy efficient construction methods

Advanced Houses 1991 - 1993– Targeted to use ½ the energy of an

R-2000 house– Incorporated innovative and

environmental benign technologies– Use of recycled materials– 50% reduction in water use– Construction waste management– Indoor air quality guidelines– Advanced houses built by teams

located across Canada– Houses sold and performance

monitored

Passive House

• Late 1980’s Wolfgang Feist cofounder of the German Passive House Institute visits the Saskatchewan Conservation House and learns about energy efficient home construction

• 1990 Germans start talking about the Passive House Standard and adopting Canadian technology

• Research Projects carried out• Passive House Standard established in 1996• 2000 on Canadian technology sold to the world as German

Engineering• First NA Passive House project 2003

Next Generation of High Performance Buildings

• Regenerative – Not only minimize environmental impacts but

actually contribute to the healing of the environment

• High quality indoor environment– Positively contribute to human health and well being – Interior daylight illumination– Visual connection with the natural environment– High indoor air quality

Regenerative Design• Design of buildings,

communities and landscapes that– Meet all energy requirements with

renewable energy– Do not produce soil, water or air

pollution – Increased natural habitat– Eliminate the heat island effect – Capture and sequester CO2 – Harvest rainwater and snow for

internal use– Internally process waste water– Reintroduce storm water and

processed waste water into the aquifer
